The present invention relates to a display apparatus, and more particularly, to a display apparatus that minimizes thickness while enhancing a sense of beauty through an innovative design.

2. Discussion of the Related Art

Recently, various flat-type display devices have been actively researched and studied as substitutes for cathode ray tube (CRT) displays. The most widely considered devices include liquid crystal display (LCD) devices, plasma display panel (PDP), field emission display (FED) devices, and light emitting display (LED) devices. The LCD device has attracted especially great attention due to its advantageous properties, such as mass production technology, simple driving means, and high picture quality.

Recent research and development are particularly being required on designs of products appealing to consumers. Consequently, efforts for minimizing the thicknesses (slimness) of LCD devices are continuously being made, and research is being conducted on a design with an enhanced sense of beauty that can induce consumers to purchase by appealing to consumers' sense of beauty.

In efforts to minimize the thicknesses of LCD devices and design development to enhance a sense of beauty that have been made to date, the existing elements have been applied as is, the structure of the elements has been minimally changed, and therefore, there are limitations in minimizing the thicknesses of the LCD devices and developing new designs of the LCD devices.

For example, a related art LCD device necessarily uses lower and upper cases to receive a liquid crystal display panel and a backlight unit therein. In addition, front and rear set covers are additionally used in the related art LCD device to manufacture products, such as a notebook computers, monitors, mobile devices, or televisions. As the lower and upper cases and the front and rear set covers for the manufactured device are inevitably used, it makes a limitation in the slimness of the display device and the advance toward the new design. Especially, the front edge parts of the liquid crystal display panel are covered with the upper case and the front set cover so that the liquid crystal display device is increased in its thickness. Also, the edge width of the liquid crystal display device may be increased so that the difference in height of the stepped portion may cause limitations in advance toward the innovative design.

SUMMARY OF THE INVENTION

Accordingly, the present invention is directed to a display apparatus that substantially obviates one or more problems due to limitations and disadvantages of the related art.

Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Hereinafter, a display apparatus according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 illustrates a display apparatus according to a first exemplary embodiment of the present invention; FIG. 2 is a cross sectional view along line A-A of FIG. 1; and FIG. 3 is an expanded view showing portion ‘B’ of FIG. 2.

With reference to FIGS. 1 to 3, the display apparatus 10 includes a display panel 110 which includes a lower substrate 112, an upper substrate 114 confronting the lower substrate 112, and a film member 116 combined with the upper substrate 114; a backlight unit 120 which emits light toward the display panel 110; a panel support member 130 which receives the backlight unit 120, and supports the display panel 110 to expose the front and lateral sides of the display panel 110 to the outside; and an adhesive member 140 which connects the display panel 110 and the panel support member 130 with each other. The display panel 110 includes the lower substrate 112; the upper substrate 114 which confronts the lower substrate 112 with a liquid crystal layer (not shown) interposed therebetween; the film member 116 which is combined with and formed on a front surface of the upper substrate 114; and a lower polarizing film 118 which is combined with and formed on a rear surface of the lower substrate 112.

The lower substrate 112 includes a plurality of gate lines (not shown), a plurality of data lines (not shown), and a plurality of pixels (not shown) which are respectively formed at crossing portions of the gate and data lines. Each pixel includes a thin film transistor (not shown) which is connected with the gate and data lines; a pixel electrode which is connected with the thin film transistor; and a common electrode which is formed adjacent to the pixel electrode and is supplied with a common voltage. Depending on a driving method of the liquid crystal layer, the common electrode may be formed on the upper substrate 114. The lower substrate 112 controls light transmittance of the liquid crystal layer by forming an electric field corresponding to a differential voltage between the common voltage and data voltage applied to each pixel.

Under the circumstance that the lower and upper substrates 112 and 114 confronts each other, the upper substrate 114 including color filters respectively provided corresponding to the pixels of the lower substrate 112 is bonded to the lower substrate 112 while being provided with the liquid crystal layer being interposed therebetween. Depending on the driving method of the liquid crystal layer, the common electrode to be supplied with the common voltage may be formed on the upper substrate 114. The upper substrate 114 filters the light incident via the liquid crystal layer by the use of color filters, and emits the color-filtered light so that colored images are displayed on the display panel 110.

A detailed structure of the lower substrate 112 and upper substrate 114 may vary according to a driving mode of the liquid crystal layer, for example, twisted nematic (TN) mode, vertical alignment (VA) mode, in-plane switching (IPS) mode, and fringe field switching (FFS) mode. The film member 116 is combined with (or attached to) the front surface of the upper substrate 114, wherein the film member 116 includes an upper polarizing film for polarizing the light emitted to the outside via the upper substrate 114. The lower polarizing film 118 is attached to the rear surface of the lower substrate 112. The lower polarizing film 118 polarizes the light emitted from the backlight unit 120 to the display panel 110.

The display panel 110 is supported by the panel support member 130 so that the front and lateral sides of the display panel 110 are exposed to the outside. Here, the front and lateral sides of the display panel 110 are exposed to the outside so that a structure (bezel) forming the front edge part of the display panel 110 can be removed, and a stepped portion of the edge part can also be removed, thereby enhancing a sense of beauty in the design of external appearance. In this case, since the lateral side of the display panel 110 is exposed to the outside, the film member 116 attached to the upper substrate 114 might be peeled off by a user's contact. To overcome this problem, as shown in FIG. 3, the upper side portions of the upper substrate 114 and each side portion of the film member 116 are formed to have inclines (CF1, CF2) with a predetermined gradient.

The upper side portion of the upper substrate 114 is manufactured to have the first incline (CF1) with a first gradient by a process, such as a chamfer. Each side portion of the film member 116 is manufactured to have the second incline (CF2) with a second gradient corresponding to the first gradient by a cutting process using a laser or cutting wheel. In this case, each side portion of the film member 116 is provided with a distance (D1) of 0.1±0.07 mm from the side portion of the upper substrate 114, preferably. Preferably, a width (W1) of the second inclination (CF2) is about 0.15±0.05 mm. Accordingly, the display apparatus 10 includes the first inclination (CF1) formed at the upper side portion of the upper substrate 114, and the second inclination (CF2) formed on each side portion the film member 116, so that the film member can be prevented 116 from being peeled off by the user's contact when the lateral side of the display panel 110 are exposed to the outside.

As shown in FIG. 4, the display apparatus 10 according to the first exemplary embodiment further includes a plurality of circuit films 150 which are combined with a pad provided in the periphery of the lower substrate 112 corresponding to the first side of the display panel 110; a printed circuit board 160 which is combined with the plurality of circuit films 150; and a deco cover 170 which is combined with the panel support member 130 to cover the pad, the plurality of circuit films 150, and the printed circuit board 160. At this time, the first side of the display panel 110 may be the first longitudinal side between the first and second longitudinal sides of the lower substrate 112.

A data driving integrated circuit (not shown) for supplying a data signal to the display panel 110 is mounted on each of the plurality of circuit films 150. On the lower substrate 112 of the display panel 110, a gate driving circuit (not shown) for supplying a gate (or scan) signal to the display panel 110 is formed by a process for forming the thin film transistor. The plurality of circuit films 150 are attached to the pad of the display panel 100 and the printed circuit board 160 by a tape automated bonding (TAB) process, wherein the plurality of circuit films 150 may be a tape carrier package (TCP) or a chip on flexible board (or chip on film; COF). Accordingly, the display panel 110 is electrically connected with the printed circuit board 160 via the plurality of circuit films 150. The printed circuit board 160 supplies various signals for displaying images on the display panel 110 while being electrically connected with the plurality of circuit films 150. On the printed circuit board 160, there are a timing controller (not shown) for controlling the driving of the display panel 110, various power circuits (not shown), and a memory device (not shown) which are mounted thereon.

The deco cover 170 is combined with the panel support member 130 corresponding to the first side of the display panel 110, and covers the pad of the display panel 110, the plurality of circuit films 150, and the printed circuit board 160, thereby preventing the pad of the display panel 110, the plurality of circuit films 150, and the printed circuit board 160 from being exposed to the outside. For this, the deco cover 170 includes hook members (not shown), wherein the hook members are formed at both lateral sides of the deco cover 170, and are combined with the panel support member 130.

As shown in FIG. 2, the backlight unit 120 includes a light-guiding plate 122, a reflective sheet 124 and an optical member 126, which are received in the panel support member 130. The light-guiding plate 122 is plate-shaped (or wedge-shaped) so as to advance the light incident onto an incidence face from a light source (not shown) toward the display panel 110. Here, the light source may include fluorescent lamps or light-emitting diodes. The reflective sheet 124 is arranged on a rear surface of the light-guiding plate 122, wherein the reflective sheet 124 reflects the light incident from the light-guiding plate 122 toward the display panel 110. The optical member 126 is arranged on the light-guiding plate 122, wherein the optical member 126 enhances the luminance properties of light advancing toward the display panel 110 from the light-guiding plate 122. For this, the optical member 126 may include at least one diffusion sheet and prism sheet among a lower diffusion sheet, a lower prism sheet, an upper prism sheet, and an upper diffusion sheet.

As shown in FIGS. 2 and 3, the panel support member 130 supports the display panel 110 so as to expose the front side of the film member 116 and the lateral side of the display panel 110 to the outside. For this, the panel support member 130 includes a set cover 131, a support cover 133, a guide frame 135, and first and second coupling members 137 and 139. The set cover 131 has such U-shaped structure as to secure a space for receiving the support cover 133 and the guide frame 135, and supports the rear margin portion of the display panel 110. The set cover 131 may be formed of plastic or metal. For enhancing the sense of beauty in the manufactured display apparatus, it is preferable that the set cover 131 be formed of a metal. For this, the set cover 131 includes a set plate 131 a and a set sidewall 131 b.

The set plate 131 a being plate-shaped functions as a rear cover of the manufactured display apparatus 10. That is, the set plate 131 a may be a rear cover of a display product, such as television or notebook computer. The set sidewall 131 b being vertically bent from the end of the set plate 131 a prepares a predetermined space, and simultaneously supports the rear margin portion of the display panel 110. At this time, the external lateral surface of the set sidewall 131 b exactly meets with the external lateral surface of the display panel 110 along the same vertical line without being stepped. The set sidewall 131 a is exposed to the outside while covering the lateral side of the guide frame 135 so that the set sidewall 131 a functions as a lateral cover of the manufactured display apparatus 10. That is, the set sidewall 131 b may be a lateral cover of a display product, such as a television or notebook computer.

The support cover 133 is received in the predetermined space prepared by the set cover 131, wherein the support cover 133 supports the guide frame 135 and receives the backlight unit 120 therein. For this, the support cover 133 includes a support plate which supports the backlight unit 120, and a support sidewall which is vertically bent from the end of the support plate. At this time, the support cover 133 may be combined with the set cover 131 by a plurality of coupling screws to be coupled to the support plate through the set plate 131 a. For realizing a good design that is slim, the support cover 133 may be removed.

The guide frame 135 is formed in a rectangular frame structure to have a

-shaped cross section. The guide frame 135 is placed on the support sidewall of the support cover 133, and is combined with the rear margin portion of the display panel 110 by the use of adhesive member 140. For this, the guide frame 135 includes a panel combining part 135 a, and a guide sidewall 135 b which is vertically bent from the panel combining part 135 a and is combined with the set sidewall 131 b.

The panel combining part 135 a is formed in a plate shape to face toward the rear margin portion of the display panel 110. At this time, the panel combining part 135 a has a groove having a predetermined depth for facilitating to form the adhesive member 140. The guide sidewall 135 b being vertically bent from one end of the panel combining part 135 a adjacent to the set sidewall 131 b is provided in the space between the set sidewall 131 b and the support sidewall of the support cover 133, and is simultaneously combined with the set sidewall 131 b.

The first coupling member 137 is formed in the guide sidewall 135 b of the guide frame 135. The second coupling member 139 is formed in the set sidewall 131 b of the set cover 131 while being coupled with the first coupling member 137. For example, the first coupling member 137 protrudes from the outer sidewall of the guide sidewall 135 b, wherein the first coupling member 137 includes a stepped surface and an inclined surface. The second coupling member 139 is hollowly formed (or recesses) with a predetermined depth from the inner sidewall of the set sidewall 131 b so that the second coupling member 139 is provided corresponding to the first coupling member 137. At this time, the stepped surface of the first coupling member 137 prevents the first coupling member 137 from being detached from the second coupling member 139, and the inclined surface of the first coupling member 137 facilitates the coupling of the first and second coupling members 137 and 139. The first and second coupling members 137 and 139 respectively have the opposite structures to be coupled with each other.

For the above explanation, the guide frame 135 and the set cover 131 are mutually combined with each other, but it is not limited to this structure. In the aspect of the design of the display apparatus 10, the guide frame 135 and the support sidewall of the support cover 133 may be mutually combined with each other. In this case, the set cover 131 may be combined with the support cover 133 by the plurality of coupling screws to be coupled to the cover plate of the support cover 133 through the set plate 131 a.

The adhesive member 140 is formed in the panel combining part 135 a of the guide frame 135, thereby combining the display panel 110 and the guide frame 135 with each other. Preferably, the adhesive member 140 is combined with the lower substrate 112 of the display panel 110 in consideration to the adhesive strength and thickness, but not necessarily. However, the adhesive member 140 may be combined with the lower polarizing film 118. The adhesive member 140 may be two-sided tape, an adhesive or other suitable means.

In the display apparatus 10 according to the first exemplary embodiment, the display panel 110 is combined with the guide frame 135 by the use of adhesive member 140, and the guide frame 135 with the display panel 110 combined therewith is combined with the set cover 131. Thus, the upper case and front set cover of the related art can be eliminated. However, since the display panel 110 is fixed to the guide frame 135 by the adhesive member 140, light leakage may occur due to the change of liquid crystal layer by the external force applied to the display panel 110 to which the adhesive member 140 is attached, or the change of liquid crystal layer by the adhesive strength of the adhesive member 140. That is, the light leakage may occur because the display panel 110 is not moved. To solve this problem of light leakage, as shown in FIG. 3, the first coupling member 137 and the second coupling member 139 are coupled with a predetermined gap (G) for the movement of the display panel 110. Thus, if the external force is applied to the display panel 110 in the display apparatus 10 according to the first embodiment of the present invention, the first coupling member 137 may be moved within the gap (G) between the first and second coupling members 137 and 139 in at least one direction among the X-axis, Y-axis, and Z-axis directions to adjust for movement or expansion of the display panel 110, thereby preventing the light leakage caused by the display panel 110 being not moved.

In the display apparatus 10 according to the first exemplary embodiment, the front and lateral sides of the display panel 110 supported by the panel support member 130 are exposed to the outside. As a result, the thickness can be reduced by removing the upper case and front set cover, which have been generally used for the related art display device. Further, the structure (bezel) forming the front edge part of the display panel 110 can be removed, and the stepped part of the edge part can also be removed, thereby resulting in an enhanced sense of beauty in the design of external appearance. Also, the inclines CF1, CF2 are formed on the side portions of the film member 116 and the upper substrate 114 so that it is possible to prevent the film member 116 combined with the display panel 110 to be exposed to the outside from being peeled off.

FIG. 5 illustrates a display apparatus according to a second exemplary embodiment. FIG. 6 is a cross sectional view along line C-C of FIG. 5. FIG. 7 is an expanded view showing portion ‘D’ of FIG. 6.

As shown in FIGS. 5 and 6, the display apparatus 20 according to the second embodiment includes a display panel 210 for displaying a stereoscopic image, wherein the display panel 210 includes a lower substrate 112, an upper substrate 114 confronting the lower substrate 112, and a film member 216 combined with the upper substrate 114; a backlight unit 120 which emits light toward the display panel 210; a panel support member 130 which receives the backlight unit 120, and supports the display panel 210 to expose the front and lateral sides of the display panel 210 to the outside; and an adhesive member 140 which connects the display panel 210 and the panel support member 130 with each other.

Except that left and right images are spatially divided by the display panel 210, and are separated by the film member 216, the display apparatus 20 according to the second exemplary embodiment is generally the same in structure to the display apparatus 10 according to the first exemplary embodiment. Thus, a detailed explanation for the other elements except the display panel 210 and the film member 216 will be omitted.

Except that the left image and right image are alternately displayed by unit of a horizontal line corresponding to a gate line or a vertical line corresponding to a data line, the display panel 210 of the display apparatus 20 according to the second exemplary embodiment is generally the same in structure to the display panel 210 of the display apparatus 20 according to the first exemplary embodiment.

The film member 216 includes an upper polarizing film 216 a which polarizes the light emitted to the outside via the upper substrate 114; and a retarder film 216 b or other functional optical film which is combined with the upper polarizing film 216 a, and separates the left image and the right image from each other. The upper polarizing film 216 a is combined with a front surface of the upper substrate 114 of the display panel 210 except a deco cover 170. At this time, each side portion of the upper polarizing film 216 a has a second inclination (CF2) having a second gradient corresponding to a first gradient of a first incline (CF1) of the upper substrate 114 by a cutting process using a laser or cutting wheel. In this case, each side portion of the upper polarizing film 216 a is provided with a distance (D1) of 0.1±0.07 mm from the side portion of the upper substrate 114, preferably. The retarder film 216 b is combined with a front surface of the upper polarizing film 216 a. At this time, each side portion of the retarder film 216 b is manufactured to have a third inclination (CF3) having a third gradient corresponding to the second gradient of the second incline (CF2) of the upper polarizing film 216 a by the above cutting process using a laser or cutting wheel. Preferably, an entire width (W2) of the second and third inclinations (CF2, CF3) is about 0.15±0.05 mm.

The above retarder film 216 b separates the left image and the right image to be displayed on the display panel 210. For this, the retarder film 216 b includes a plurality of first retarder patterns (RF1) which are overlapped with the horizontal or vertical line of the display panel 210 on which the left image is to be displayed; and a plurality of second retarder patterns (RF2) which are respectively formed between each of the plural first retarder patterns (RF1) while being overlapped with the horizontal or vertical line of the display panel 210 on which the right image is to be displayed. The first and second retarder patterns (RF1, RF2) reciprocally changes optical axes of the left image and the right image to be emitted from the display panel 210 to the outside.

Except that the stereoscopic image is displayed on the display panel 210, and the film member 216 includes the retarder film 216 b, the display apparatus 20 according to the second exemplary embodiment of the present invention is generally the same in structure to the display apparatus 10 according to the first exemplary embodiment so that the display apparatus 20 according to the second exemplary embodiment can apply the same effects as those of the first exemplary embodiment to a stereoscopic image display apparatus.

FIG. 8 illustrates a display apparatus according to a third exemplary embodiment of the present invention. FIG. 9 is a cross sectional view along line E-E of FIG. 8. FIG. 10 is an expanded view showing portion ‘F’ of FIG. 9.

With reference to FIGS. 8 to 10, the display apparatus 30 according to the third exemplary embodiment includes a display panel 110 which includes a lower substrate 112, an upper substrate 114 confronting the lower substrate 112, and a film member 116 combined with the upper substrate 114; a backlight unit 120 which emits light toward the display panel 110; a panel support member 130 which receives the backlight unit 120, and supports the display panel 110 to expose the front and lateral sides of the display panel 110 to the outside; an adhesive member 140 which connects the display panel 110 and the panel support member 130 with each other; and a panel protection member 350 formed on the edge part of the display panel 110 to protect the edge part of the display panel 110.

Except the panel protection member 350 of the display apparatus 30, the display apparatus 30 according to the third exemplary embodiment is generally the same in structure to the display apparatus 10 according to the first exemplary embodiment so that a detailed explanation for other elements except the panel protection member 350 will be omitted, and the same reference numbers will be used throughout the drawings to refer to the same or like parts.

The panel protection member 350 is formed in the edge part of the display panel 110 corresponding to the second, third, and fourth sides except the first side of the display panel 110. As shown in FIG. 4, a plurality of circuit films 150, and a printed circuit board 150 combined with the circuit films 150 are arranged in a pad which is provided in the periphery of the lower substrate 112 corresponding to the first side of the display panel 110. The portion corresponding to the first side of the display panel 110 is covered by a deco cover 170, so it is unnecessary to form the panel protection member 350 at the portion corresponding to the first side. The panel protection member 350 may be formed of silicon-based or UV curable sealant (or resin). In consideration to tack time, a UV curable sealant may be used. In this case, viscosity of the sealant is 1500˜30000 cps, but it is not limited to the above range. The viscosity of the sealant may be selected depending on the process time. Also, the panel protection member 350 may be colorless (or transparent) or colored (for example, blue, red, or black), but it is not limited to the above example. The color of the panel protection member 350 may be selected depending on the design of the display apparatus. To prevent the light from leaking in the lateral side of the display panel 110 by the internal total reflection occurring in the lower substrate 112 of the display panel 110, the panel protection member 350 may be formed of colored resin or light-shielding resin.

As shown in FIG. 10, the panel protection member 350 according to a first example is formed on the edge part of the display panel 110 including the entire side portions of the lower and upper substrates 112 and 114, and the partial side portion of the film member 116. At this time, the upper portion of the panel protection member 350 covers the partial side portion of the film member 116, that is, the lower side portion of the second inclination (CF2).

As shown in FIG. 11, the panel protection member 350 according to a second example is formed on the edge part of the display panel 110 including the entire side portions of the lower and upper substrates 112 and 114 and the film member 116. At this time, the upper portion of the panel protection member 350 covers the entire side portion of the film member 116, that is, the entire side portion of the second inclination (CF2).
